Danger to life from electric shock if the Sunny Central is damaged
Operating a damaged Sunny Central can lead to hazardous situations that result in death or serious injuries due to
electric shock.
• Only use the Sunny Central when it is in a technically faultless condition and safe to operate.
• Regularly check the Sunny Central for visible damage.
• Make sure that all external safety equipment is freely accessible at all times.
• Make sure that all safety equipment is in good working order.
• Wear suitable personal protective equipment for all work on the Sunny Central.

Danger to life from electric shock when entering the PV field
The insulation monitoring with GFDI, Remote GFDI or soft grounding does not provide protection from injury when GFDI
is activated. PV modules which are grounded with GFDI discharge voltage to ground. Entering the PV field can result
in lethal electric shocks.
• The inverter must be installed in a closed operating area.
• Before entering the PV field, switch the PV array to insulated operation.
• Ensure that the insulation resistance of the PV field is greater than 1 k Ω .
Danger to life from electric shock if the Sunny Central is not locked
If the Sunny Central is not locked, unauthorized persons have access to live components carrying lethal voltages.
Touching live components can result in death or serious injury due to electric shock.
• Always close and lock the Sunny Central.
• Remove the key from the door locks and from the key switch.
• Store the key in a safe place.
• Ensure that unauthorized persons do not have access to the PV system.
Danger to life due to blocked escape routes
In hazardous situations, blocked escape routes can lead to death or serious injury. Opening the doors of two
Sunny Central inverters located opposite each other blocks the escape route. It is imperative that the escape route is
freely accessible at all times.
• An escape route of at least 500 mm width must be available at all times. Make sure the minimum passage width
of the escape route meets local standards.
• Do not place any objects in the escape route area.
• Remove all tripping hazards from escape routes.
• If two Sunny Central inverters have been installed facing each other, never open the doors of both inverters
simultaneously.
Risk of fire due to failure to observe torque specifications on live bolted connections
Failure to follow the specified torques reduces the ampacity of live bolted connections so that the contact resistances
increase. This can cause components to overheat and catch fire.
• Ensure that live bolted connections are always tightened with the exact torque specified in this document.
• When working on the device, use suitable tools only.
• Avoid repeated tightening of live bolted connections as this may result in inadmissibly high torques.
